Ok, read the few reviews, and from what I gathered, It's warm for a hybrid, decent resolve, and a close stage. Speculating, it has room for mods, they'll probably come out with a fully balanced, and we'll see some new dacs for pairing. It's a $250 amp, with a 4pin xlr. I have a nicer $100 trs for my hd650, but with this, I would have to make an additional xlr purchase if I didn't want to use 3.5. I don't know, maybe people who mod could have fun trying to make it balanced. Oh, by the way, I wrote this in the Blueridge mountains and soon I'll be in the hills of Tallahassee. (Seminole indian meaning 7 hills). I think the elevation and lack of oxygen, may be affecting my judgement.
